Analysis And Construction Of The Logistics Information Platform Based On Web Service

With the development of distributed components and Internet technology, there is an urgent need to establish a new distributed computing technology in the Internet, which develops a new generation of Internet-based distributed system. First of all, this technology must be independent of any manufacturers, platforms and languages; second, it must provide better interoperability and integration than traditional; finally, it is easy for programmers to develop, deploy and use. This is an important reason for the rise of Web Service, which fully meet all of the conditions. The structure of Web Service can truly resolve the current problem that each distributed solution can not conquer in order that each component model, Web system and even general application all can communicate and integrate each other.The paper first researches the current situation and the problems of the logistics informatization, then study the SOA and the technique-web Service. Based on these researches, the paper describes the whole architecture of the platform. After analyzes these Service, the paper finds which Service can use the SOA to design, and then design all functional modules and optimize performance and security of the system, finally construct a logistics information platform based on Web Service.In system, we develop primary functions using the form as web Service. Web Service enable relevant enterprises to structure and integrate every web service that this system offers fast and conveniently, to ease the enterprises application maintain working, and the data interchange between the application systems becomes easier and easier to implement. We develop the system by C# language in .NET platform, The interaction language in this system is offered by standard SOAP, thus the system reduces the communication protocol kind that must be supported for the client, and the configure demand of the client equipment. What's more, realize communication of different application in different platform; also lay the foundation for the development of system and business. Not only the architecture of the system conquers the defects of traditional plan but more open.To enhance the efficiency of web service, the paper introduced Web Service Improved System based on SOAP, we compress it after serializing SOAP response message on the server and decompress it before deserializing SOAP message on the client. The mentioned process above is the SOAP Extension. In order to deal with the challenges and threats that Web Service faced in security, WS-Security, XML encryption, XML signature and XKMS are researched and summarized pertinently.
